hi.
what do you mean by pining or sending privmsgs to "all users"? on the network? on local server?
or do you mean only opers should get something? what if a channel has it's own eggdrop and that is triggered by !help, would the opers get a "ping" ?
i presume, you didn't think enough about this.
And what would be the flood protection for that specific module? I can imagine a user typing !999 endlessly just to annoy IRCops.
Would unregistered users be able to use it?
And ping all users would be a bit bad for the users that have nothing to do with network administration.
still.. this can be done with a bot.. why make and add such module to the ircd?:o
and i still don't get the purpose of this command.. i could imagine a !help command in a specific channel like in #help, someone join, no ops or helpers online, so someone would use !help and then it would notify other opers..
but as i said.. an eggdrop could handle such things.
